Over the past decade, exoplanet surveys have discovered that many other solar systems teem with super-Earths on sub-Mercury orbits. A major open question is whether these super-Earths formed on their observed close-in orbits or formed at a wider separations and migrated in. I will present recent work on what the orbital and compositional properties of super-Earths in inner solar systems can reveal about super-Earths’ origins and more generally about the physical processes driving the formation and evolution of planetary systems.
